assess a trainee’s performance on a specific BACB 5th edition task list skill while ensuring their comfort during evaluation

Select one item from the BACB® 5th edition task list. Pinpoint a specific behavior or output/permanent product related to the task list item, operationally define it, and determine how you would evaluate a trainee's performance on the skill, both initially and ongoing. Would you include a checklist, BARS, or self-assessment? Would you use any fundamental measures or sampling procedures? How will you make your trainees comfortable being assessed on this skill?
